China leading optical fiber and cables, special cables, submarine cable manufacturer JSZT's subsidiary SHZT Superconducting Technology Co., Ltd. is mainly engaged in the R & D and manufacturing of superconducting power application products.
After years of development of superconducting technology, the domestic second-generation high-temperature superconducting material preparation technology has matured, the product performance has reached the international level, and the cost has dropped significantly. Demonstration project of superconducting current limiter.
Superconducting cables have large capacity, low loss (near zero power transmission loss), energy saving and environmental protection, and traditional copper and aluminum cables cannot compare superior performance; superconducting current limiters have low operating loss and fast response speed, which can quickly and effectively limit power grid faults. The ability of electric current escorts the normal operation of the transmission and distribution network.
With the continuous progress and development of superconducting application technology in the field of power transmission, superconducting cables and superconducting current limiters are gradually replacing conventional cables and high-loss fault current limiting devices, and become an indispensable key technology in the future power system .
